Does this ‘Game of Thrones’ season 6 teaser validate a Jon Snow theory?

The first Game of Thrones teaser trailer for season 6 is here, and if those visions are any indication its about to get bloody.

Jon Snowwho already graced the teaser posterand many of the other characters who have been dealt horrible fates serve as a backdrop of what will likely be one of many ominous conversations between Bran Stark (Isaac Hempstead-Wright) and the Three-Eyed Raven (Max von Sydow), who have been training his Sight abilities off-screen over the past season.

We watch, we listen, and we remember, the Three-Eyed Raven says to Bran. The past is already written. The ink is dropping.

They have no idea whats going to happen, Bran answers after a lingering shot of Jons dead body.

While Bran and the Three-Eyed Raven never mention any of the characters by name, its evident that theres a particular focus on Jon. But that last shot in particularwhich pairs Jons final shot with Bran full into warging modeoffers up an intriguing question. Is that a nod to the theory that Jon could warg into Ghost (an ability Jon and all of the Starks possess) after his death, or is the show just messing around with us?
